The Company will file amended reports as soon as practicable. PART II - OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS. GENERAL The business of the Company's hazardous and industrial waste services is continuously regulated by federal, state, provincial and local provisions that have been enacted or adopted, regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment. The nature of the Company's businesses results in its frequently becoming a party to judicial or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues that are involved generally relate to applications for permits and licenses by the Company and their conformity with legal requirements and alleged technical violations of existing permits and licenses. The Company does not believe that these issues will be material to the Company's operations or financial condition. At May 31, 2000, subsidiaries of the Company were involved in two proceedings relating primarily to activities at waste treatment, storage and disposal facilities where the Company believes sanctions involved in each instance may exceed $100,000. The Company believes that the ultimate disposition of these issues will not have a materially adverse effect upon the Company's consolidated financial position or results of operations. From time to time, the Company is named as a defendant in various lawsuits arising in the ordinary course of business, including proceedings wherein persons claim injury resulting from the use of the Company's parts cleaner equipment and/or cleaning products, other matters involving personal injury and property damage claims and employment-related claims. A number of such legal proceedings are currently pending in various courts and jurisdictions throughout North America. Based on the Company's assessment of known claims and its historical claims payment pattern, and discussions with internal and outside legal counsel and risk management personnel, the Company believes that there is no proceeding pending against the Company relating to such matters arising out of the ordinary course of business that, if resolved against the Company, would have a materially adverse effect upon the Company's consolidated financial position or results of operations. In the United States, CERCLA imposes financial liability on persons who are responsible for the release of hazardous substances into the environment. Present and past owners and operators of sites which release hazardous substances, as well as generators and transporters of the waste material, are jointly and severally liable for remediation costs and environmental damage. At May 31, 2000, the Company had been notified that it was a potentially responsible party in connection with 50 locations in its hazardous waste management and other businesses. Page 3 The Company continually reviews its status with respect to each location and the extent of its alleged contribution to the volume of waste at the location, the available evidence connecting the Company to that location, and the numbers and financial soundness of other potentially responsible parties at the location. Based upon presently available information, the Company does not believe that potential liabilities arising from its involvement with these locations will be material to the Company's operations or financial condition. CHAPTER 11 FILING As previously announced by the Company in a Current Report on Form 8-K filed on June 19, 2000, Safety-Kleen Corp. and 73 of its wholly owned domestic subsidiaries filed a voluntary petition for reorganization under Chapter 11 of Title 11 of the United States Code on June 9, 2000. The petition was filed in the United States Bankruptcy Court for the District of Delaware (Case No. 00-2303 (PJW). Management of the Company continues to operate the business of the Company as a debtor in possession under 11 U.S.C. ss.ss. 1107 and 1108. In this proceeding, the Company and its subsidiaries will seek approval of a Plan for Reorganization and intend to implement the Plan for Reorganization upon obtaining court approval of the Plan. Pursuant to the automatic stay provision of Section 362 of the Bankruptcy Code all litigation matters are currently stayed. SAFETY-KLEEN (PINEWOOD), INC. The Company's reports on this matter contained in the Company's Report on Form 10-K for the twelve months ended August 31, 1999 and on Form 10-Q for the quarters ended November 30, 1999 and February 28, 2000, are incorporated herein by reference thereto. On May 4, 2000, Pinewood petitioned the South Carolina Supreme Court for a writ of certiorari from the state Court of Appeals decision. On June 9, 2000 (on the same day but after Pinewood filed its petition for bankruptcy protection in the United States District Court for the District of Delaware), DHEC issued an Emergency Order finding that Frontier Insurance Company - which is the issuer of bonds used to provide for Pinewood's closure cost, post-closure cost, and third party liability financial assurance - no longer meets regulatory standards for bond issuers. Based on this finding, DHEC ordered that Pinewood cease accepting waste for disposal by August 28, 2000, unless it could provide acceptable alternative financial assurance by June 27, 2000. On June 13, 2000, the South Carolina Supreme Court denied Pinewood's petition for a writ of certiorari and the decision of the Court of Appeals became final. On June 14, 2000, DHEC sent notice by letter to the Pinewood Facility directing that Pinewood cease accepting waste for disposal in 30 days - by July 14, 2000 - and submit a closure plan. DHEC based this directive on the then-final decision of the Court of Appeals that all non-hazardous waste disposed at Pinewood should be counted against Pinewood's hazardous waste capacity limit and DHEC's resulting conclusion that there is no remaining permitted capacity at Pinewood. Page 4 On June 22, 2000, DHEC sent notice by letter to Pinewood that under the Court of Appeals decision, financial assurance regulations for cleanup and/or environmental impairment restoration at hazardous waste treatment, storage, and disposal facilities were vacated and, therefore, this financial assurance for Pinewood must be provided in accordance with the DHEC Board Order dated May 19, 1994. The June 22, 2000 letter further directed that within 15 days Pinewood provide DHEC with information on how Pinewood would comply with the May 19, 1994 DHEC Board Order including payment into the GSX Contribution Fund. As of May 31, 2000, the GSX Contribution Fund contained $18,748,552.05, which means that under the June 22, 2000 DHEC letter Pinewood would be required to currently pay approximately $68 million into the GSX Contribution Fund, as well as make payments of approximately $14 million each year for the next four years to reach the full funding requirement. On July 7, 2000, Pinewood filed a legal action in the United States District for the District of Delaware against the State of South Carolina, DHEC, DHEC Board Chairman (Bradford W. Wyche) and DHEC Commissioner (Douglas Bryant) under the caption: In Re: Safety-Kleen Corp., et al., Debtor-Chapter 11 Cases, Case No. 00-2303 Jointly Administered - Adversary Proceeding No. A-00-698, C.A. No. 00-637. In this action Pinewood seeks to stay and/or enjoin DHEC and the State of South Carolina from enforcement of the previously-described directives to Pinewood set forth in the June 9, 2000 DHEC Emergency Order, the June 14, 2000 DHEC letter to Pinewood, and the June 22, 2000 DHEC letter to Pinewood upon the grounds that the actions of DHEC are invalid under various provisions of the United States Constitution and/or violate the automatic stay provision of the United States Bankruptcy Code and/or should be enjoined under the equitable powers of the Bankruptcy Court. As an alternative cause of action, Pinewood demanded that it be compensated for the taking of its property without just compensation under provisions of the Constitutions of the United States and the State of South Carolina. On July 10, 2000, the United States District Court for the District of Delaware issued an Order restraining DHEC and the State of South Carolina from enforcing its anticipated closure of the Pinewood facility pursuant to the June 14, 2000 DHEC letter. On July 12, 2000 the United States District Court for the District of Delaware issued an Order transferring the case to the United States District Court for the District of South Carolina and ordering that the Order of July 10, 2000 remain in full force and effect pending a ruling from the United States District Court for the District of South Carolina on Pinewood's request for a preliminary injunction against DHEC and the State of South Carolina. If none of the challenges to the decision of the Court of Appeals is successful, enforcement of the decision could have a material adverse impact upon the Company's financial position. MATTERS RELATED TO INVESTIGATION OF FINANCIAL RESULTS The Company's report on this matter contained in the Company's Report on Form 10-Q for the quarter ended February 28, 2000 is incorporated herein by reference thereto. In the Report on Form 10-Q for the quarter ended February 28, 2000 the Company reported that it anticipated that additional Federal Class Actions may be filed. Additional Federal Class Actions that have Page 5 been filed are as follows: No. CASE NAME COURT DOCKET # DATE OF CLASS PERIOD FILING 1.
